Teaching Item: Understanding Built-In Class Attributes in Python

Class: Bachelor

Objective:

Students will understand the concept of built-in class attributes in Python, learn about commonly used built-in class attributes, and how to access and utilize them effectively.

Materials Needed:

• Python interpreter or IDE
• Projector

1. Introduction to Built-In Class Attributes (10 mins)

• Define built-in class attributes:
  • Built-in class attributes are attributes that are automatically created and available for every class in Python.
  • They provide useful information about the class and its instances.
• Discuss the importance of built-in class attributes in programming:
  • They provide metadata about the class and its instances.
  • They can be used for introspection and debugging purposes.

2. __dict__ Attribute (15 mins)

• Explain the __dict__ attribute:
  • The __dict__ attribute is a dictionary containing the namespace of the class or instance.
  • It stores the attributes and methods of the class or instance as key-value pairs.
• Demonstrate how to access and manipulate the __dict__ attribute:
  • Show examples of accessing and modifying attributes using the __dict__ attribute.

3. __doc__ Attribute (10 mins)

• Introduce the __doc__ attribute:
  • The __doc__ attribute contains the docstring of the class or instance.
  • Docstrings are documentation strings used to describe the purpose and usage of the class or method.
• Show how to access and display the docstring using the __doc__ attribute:
  • Explain the importance of writing descriptive docstrings for classes and methods.

4. __name__ and __module__ Attributes (15 mins)

• Discuss the __name__ and __module__ attributes:
  • The __name__ attribute stores the name of the class or module.
  • The __module__ attribute stores the name of the module where the class is defined.
• Show examples of accessing these attributes:
  • Demonstrate how to access the class and module names using these attributes.

5. __bases__ Attribute (10 mins)

• Introduce the __bases__ attribute:
  • The __bases__ attribute contains a tuple of base classes from which the class inherits.
  • It is useful for examining the class hierarchy and inheritance relationships.
• Show examples of accessing and iterating through the base classes using the __bases__ attribute.

6. Exercise (10 mins)

• Provide a simple programming exercise where students:
  • Create a class with custom attributes and methods.
  • Access and manipulate the built-in class attributes (__dict__, __doc__, __name__, __module__, __bases__) for introspection.

7. Conclusion (5 mins)

• Recap the key points covered in the lesson:
  • Built-in class attributes provide metadata about classes and instances in Python.
  • Commonly used built-in class attributes include __dict__, __doc__, __name__, __module__, and __bases__.
• Encourage students to explore additional built-in attributes and their uses in Python.
